Choke and Kill Hoses
API Spec 16C Flexible Hose Assemblies for Oilfield Drilling Applications
Choke and kill hoses are generally used to connect kill manifolds or choke manifolds with drilling spools and connect mud tanks with accumulators on oil rigs or drilling ships, in order to deliver oil, gas, mud and other high-pressure media.
Features
- The reinforcement layer of the drilling hose adopts imported high-strength steel wires.
- The hose’s inner rubber layer adopts imported rubber and our company’s special formula, and can withstand high-speed flows of oil- or water-based mud as well as extreme weathers. The formula can be adjusted based on transported media.
- The flexible line can work for 30 minutes under the rated pressure and in 704℃ fire.
- Flange joints at the hose end adopt anti-corrosively and thermally treated 45K/60K/75K materials. The joints are swivel-type and forged with our company’s patented technology. With identical bore diameters, the couplings can be connected to the tube without leading to choked and eddy flows and cut loss.
- The drilling hose is sheathed in stainless steel, anticorrosive and antistatic.
Media Delivered: oil- and water-based mud and fluids containing H2S
